ice: Add VF promiscuous support
Implement promiscuous support for VF VSIs. Behaviour of promiscuous support
is based on VF trust as well as the, introduced, vf-true-promisc flag.
A trusted VF with vf-true-promisc disabled will be the default VSI, which
means that all traffic without a matching destination MAC address in the
device's internal switch will be forwarded to this VF VSI.
A trusted VF with vf-true-promisc enabled will go into "true promiscuous
mode". This amounts to the VF receiving all ingress and egress traffic
that hits the device's internal switch.
An untrusted VF will only receive traffic destined for that VF.
The vf-true-promisc-support flag cannot be toggled while any VF is in
promiscuous mode. This flag should be set prior to loading the iavf driver
or spawning VF(s).
